To all tbhom it may concern..-

Be it known that I, HOLSTEIN W. WEBB,a citizen of. the United States,residing at C- lumbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Electrically-ControlledGas-Burners and Pilot-Lights, of which the following is a specification.

My invention relates to the improvement of electrically-controlledgas-burners and pilotlights; and the objects of my invention are toprovide an improved construction of valve and controlling mechanismwhereby the flow. of gas at the illuminating-burners and pilotburner isregulated by the opening and closing of an electric circuit and toproduce certain improvements in details of construction and arrangementof parts which will be more fully pointed out hereinafter. These objectsI accomplish in the manner illustrated in the accompanying drawings, inwhich- Figure 1 is an outer side elevation of the valve-containingsection of the gas-supply pipehaving my improvement thereon. Fig.

pipe and-one of the gas-burners in connection therewith. Fig. 3 is anenlarged detail view in elevation of my improved valve. 'Fig. 4 is asimilar view of said valve, taken at right angles with that shown inFig.3; and Fig. 5 is a central vertical section on line as 09 of Fig. 1, thevalve-containing section being shown continued past the pilot-pipeoutlet.

Similar numerals refer to similar throughout the several views.

1 represents a vertically-arranged gas-supply pipe, which in its lowerend portion may be provided with laterally or radially extendingpipe-arms 2, from which rise suitable illuminating-burners 3. Includedin the supply-pipel is a gas-conducting pipe-section 4, which is alsoutilized as a valve-casing. This pipe section 4 'is provided throughoutits length and preferably on opposite sides of its center with gas waysor passages 5 and 6, the latter being comparatively small. J ournaledparts transversely in the pipe-section 4 in a correspondingly-shapedopening therein is the body of a conical valve 7, the latterintersecting the main passage 5 and smaller pas- 2 is a similar view atright angles with that shown in Fig. 1 and showing the pilot-light sage6.

usual manner.

This valve has projecting outward from its smaller end a short groovedextension8 and from its larger end a slightly-reduced extension 9. Onthe latter are carried separated inner and outer ratchet-wheels 10 and11, the teeth of one projecting in the opposite direction with those ofthe other. That portion of the valve 7 which is opposite or intersectsthe main gas-passage 5 of the pipesection 4 is formed with acomparatively large opening 12, and that portion of the periphery of thevalve which intersects the smaller passage 6 is formed with twooppositely-located grooves or peripheral recesses 13. From theserecesses or grooves 13 lead to the main valve-opening 12 comparativelysmall surface or peripheral grooves 14. In order to insure the valveagainst withdrawal from its seat in the pipe-section 4, 1 preferablyemploy a suitable spring-strip 15, one end of which engages the groovedor recessed surface of the.

adapted to be connected with a suitable circuit-breaking button througha battery in the Beneath the magnet-spools I fulcrum to the pipe-section4 an armature bar or plate 19, the latter being provided near one endwith an upwardly-extending pawl-carrying arm 20, the outer hook end ofwhich is adapted to successively engage the teeth of the ratchet-wheel10, over which said pawl projects in the manner indicated more clearlyin Fig. l of the drawings. The armature-bar 19 is also provided with anupwardly-extending stop-pin 22, which is adapted when said armature-baris drawn upward to come into contact with a tooth of the outerratchetwheel 11, thereby preventing the overthrow of said ratchet wheelsor preventing the movement of the same more than the distance of onetooth at one upward movement of the armature-bar.

It will be observed that the above-described valve-operatingmechanism,consisting of the magnet, the armature-bar, ratchet-wheels,

and connected parts, is the same or substantially the same as that shownin my former patent, No. 679,197, issued under date of July extendingarm 23 of a downwardly gas-conducting tube 24. This tube 24 is providedat its lower end with an outwardly and thence upwardly extendingburner-arm 25. This burner-arm 25, which is provided at its upper endwith a suitable pilot-burner 26, is, as shown, arranged to extendbetween two of the burners 3 in such position that when the same islighted and the flame thereof is at proper height gas from said burnerswill be ignited. In regulating the supply of gas through the passage 6from the upper section of the pipe 1 Iemployaregulating valvescrew 27,which enters a threaded opening in the pipe-section 4 and the inner endof which is adapted to be projected the desired distance within thepassage 6.

In order to illustrate the operation of my device, we will assume thatthe valve 7 is turned to the position indicated in Fig. 5 ot' thedrawings, in which position the passage 6 is in communication with thecentral portions of the oppositely-located valve-grooves 13 and that thepassage 5 is closed from the fact that it is intersected by theunperforated portions of said valve. It will be observed, however, thatthe gas-supply through the passage 6 and the upper groove 13 will becarried through one of the grooves 14 to the main valve-opening l2,thence through the remaining groove 14 to the under side groove 13 downthrough the continuation of the passage 6 and through the pilot-tube 24The limited supply of gas thus provided the burner-head of thepilot-tube is adapted to maintain a comparatively small light at saidburner-head. By temporarily closing the circuit through themagnet-spools 17 it is obvious that the armature-bar 19 will be drawnupward toward the cores of said magnets, with the result that thepawl-carrying arm 20 will be thrown outward sufficiently to cause theratchet-wheel 10 to move, through engagement of the pawl 21 therewith,the distance of one tooth. This partial rotation thus imparted to theconical valve 7 opens communication between the main passage 5 and mainvalve-opening 12, and owing to the extentof the recesses 13communication of the passage 6 with said recesses is not cut F off bysaid partial rotation of the valve. As a result of the above-describedoperation of said valve not only is gas furnished through the passage 5to the illuminatingburners 3, but an increased gas-pressure is providedthe lower portion of the passage 6 through the groove connection 14 ofthe lower valve-groove 13 and the main opening 12. This increased supplyof gas to the passage 6 and pilot-tube 24 25 results in extending theflame at the pilot-burner head 26 and insuring the lighting therefrom ofthe gas which is escaping from the heads of the burners 3.

This operation being accomplished and the armature-bar having dropped toits normal position, the circuit is again closed through the magnets,with the result that a corresponding rotation of the valve is attained,whereby the valve-grooves 13 are thrown out of communication with thepassage 6, although the main valve-opening 12 still remains incommunication with the passage 5, owing to the size of saidvalve-opening. By this operation itwill be observed that gas will be outoifentirely from the pilot-tube 24 25, whilev the flames at theilluminating-burner heads will continue. A third closing of the electriccircuit results in the manner heretofore described in another partialrotation of the valve 7, which again brings the passage 6 intocommunication with the valve-grooves 13 and results in the gas at theburner-head of the pilot-tube igniting. A fourth closing of the circuitso turns the valve 7 as to cut off communication between the passage 5and valve-opening 12, thereby extinguishing the lights at the burnersand leaving a comparatively small flame at the pilot-burner.

From the above-described construction and operation it will be seen thatthe means which I employ for controlling the supply of gas attheilluminating-burners and pilot-burner are simple and effective.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In an electrically-controlled gas-burner and pilot-light, thecombination with a gas-supply pipe, and illuminating-burner supportingarms leading therefrom, of a pipe-section included in said supply-pipe,said pipe-section having comparatively large and small passagestherethrough, a gas-conducting tube having a burner-head adjacent to oneof the illuminating-burners, said tube leading from the smaller passageofsaid pipe-section, a rotatable valve intersecting said pipe-sectionand its passages, said valve having a large opening therethrough andseparated peripheral grooves, the former adapted to communicate with thelarger passage and the latter with the smaller passage of saidpipe-section, grooves connecting the large opening of the :valve andsaid separated grooves, and means :-for imparting successively partialrotations gto said valve, substantially as specified.
